New stones!!!

Good afternoon!
I need a help, you know these stones?
I won these two stones yesterday, a former barber in my neighborhood, but he does not know and not me.
I used them yesterday with a Philharmonic 6 / 8, first I used a darker and then the yellow, much like the result, I do not know which stone is thinner and it is thicker, the touch and the two seem fine, entnao I used the dark with the first 30 laps and then 30 more in yellow.
Help me please.

They are beautiful but I've never seen any of them before.
Where are you from?
Maybe they are easier to determine if we know the region?

I'm from Brazil, but I believe they are not in Brazil.
They are very old ones around 20 years, this season had plenty of material imported, this season and had many knife Solingen Philharmonic.
Here in Brazil was never to produce anything to razors, so I believe them to be imported even
Thanks

Interesting looking stones. I don't know what they could be either. On the yellow stone, I'd be curious to know whether the spots are surface stains or if after lapping the stone they would remain.

They are patches of the same stone.
I ****ed the stone with water sandpaper 400, to see just that and she continued with the stains, the stains are of course part of it.
Anyone know?
Thanks

The side view of the yellow stone shows little white specks. Those specks look similar to a fired clay composite such as pottery or a brick. The top of the dark stone has similar characteristics to a fired barber hone. If you lap a Swaty barber hone for example, the surface looks similar although on the Swaty, the aggregated appearance is smaller and of course the color of your darker stone is different than the color of a Swaty (a dark brown/red).

I'm wondering if the two "stones" you have are some sort of kiln fired composite in other words, man made.

The dark one does look like a barber hone. The other something else but I don't know what. What are the dimensions of the hones .... length and width ?

The dark one reminds me of flooring and counter-top materials we call granito and terrazzo.

As Brasil apparently lacked interior hone industry and imported hones were maybe scarce and expensive, I can imagine people looking for usable alternatives in everyday materials around them. Actually I quite like the idea of people baking their own hones as a pottery by-product, or cutting them from counter-top leftovers.

Whatever they are, I agree they are quite handsome!
